Abstract:
A lab experiment was carried out at Entomology laboratory, College of Agriculture and field experiment was carried out at College farm, College of Agriculture, Rajendranagar, PJTSAU, Hyderabad to study the physical and phytotoxic compatibility of new generation insecticides and fungicides on maize. Physical compatibility of four insecticides viz., lambda cyhalothrin 4.6% + chlorantraniliprole 9.3% ZC, chlorantraniliprole 18.5% SC, flubendiamide 39.35% SC, azadirachtin 1500 ppm and two fungicides azoxystrobin 18.2% + difenoconazole 11.4% SC, carbendazim 12% + mancozeb 63% WP was evaluated by using jar compatibility test in laboratory and found that all the eight combinations were physically compatible. The pH of insecticides and fungicides was evaluated by using digital pH meter, none of the solution was extremely acidic nor extremely alkaline. The phytotoxic incompatibility due to combination of insecticides and fungicides on maize crop was observed by spraying combination solution on ten selected plants and found that the combinations did not produced any phytotoxic symptoms like chlorotic leaf margins, reddish or purplish veins, wrinkled leaves, necrosis, stunted growth, wilting, whiplashing at 3, 7, 14 days after spraying on maize crop.
